Oracle PL/SQL Trigger Tutorial
An Oracle PL/SQL trigger is a stored program that is automatically executed or fired when a DML or DDL statement event occurs. Triggers are used to maintain the integrity of the data, enforce business rules, and validate user input. A trigger can be either a row level trigger or a statement level trigger. Row level triggers execute once for each row affected by the triggering event. Statement level triggers execute once for each statement.PL/SQL is a procedural language that has strong integration with the Oracle Relational Database Management System. Triggers are a special type of stored procedure that is automatically executed when an event occurs in the database. Events can include inserts, updates, or deletes. A trigger can be defined to fire once for each row that is inserted, updated, or deleted.An Oracle PL/SQL trigger is a stored procedure that is automatically executed in response to an event. The event can be a DML statement, DDL statement, or database operation. Triggers are useful for enforcing business rules, data integrity, and auditing. In this tutorial, you will learn about the different types of triggers, how to create them, and how to use them.A trigger is a stored procedure in database which automatically invokes whenever a specified event occurs. In terms of Oracle PL/SQL, a trigger is a stored procedure that gets executed automatically when an INSERT, UPDATE or DELETE operation takes place on a given table.There are two types of triggers in Oracle: Row level triggers and Statement level triggers. Row level triggers fire each time when the triggering event happens for each row. So, if you have 10 rows to insert/update/delete, then the row level trigger will fire 10 times. On the other hand, statement level triggers fire only once when the triggering event happens regardless of how many rows are inserted/updated/deleted.Triggers can be used for various purposes like data validation, auditing etc. You should use them very carefully as they can impact the performance of your database if not used properly.An Oracle PL/SQL trigger is a code that is automatically executed in response to an event that occurs in the database. Triggers can be defined on both database tables and database views. A trigger is associated with a table or view and is activated when a DML operation (INSERT, UPDATE, or DELETE) is performed on that table or view.
